Torus fx upper end of left ulna, subs for fx w routn heal

This code describes a buckle fracture, or torus fracture, affecting the upper portion of the left ulna bone. This type of fracture is characterized by a compression injury where the bone cortex buckles but does not completely break, often seen in pediatric patients. The "D" seventh character indicates that the patient is in the healing phase and receiving follow-up care for the fracture.

This code is appropriate for subsequent encounters when a patient with a previously diagnosed torus fracture of the upper left ulna is receiving routine follow-up care. This includes appointments for cast changes, X-ray evaluations to monitor healing progress, or physical therapy during the normal healing period. It should be used when there are no complications or delayed healing.

• Ensure the fracture is specifically of the upper end of the left ulna and is a torus type.
• The "D" seventh character is crucial for subsequent encounters during routine healing; do not use for initial treatment or malunion/nonunion.
• Always verify laterality (left vs. right) and the specific bone/location of the fracture.
